The word(s) "extravagance" appears 4 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) And it is He Who produces gardens trellised and untrellised, and date-palms, and crops of different shape and taste (their fruits and their seeds) and olives, and pomegranates, similar (in kind) and different (in taste). Eat of their fruit when they ripen, but pay the due thereof (its Zakat according to Allah's Orders 1/10th or 1/20th) on the day of its harvest, and waste not by extravagance . Verily, He likes not Al-Musrifun (those who waste by extravagance),

(2) O Children of Adam! Take your adornment (by wearing your clean clothes), while praying and going round (the Tawaf of) the Ka'bah, and eat and drink but waste not by extravagance, certainly He (Allah) likes not Al-Musrifun (those who waste by extravagance).
